Helmhotz resonators for audiophile at almost no cost and without calculus...


The importance to treat the room if you have speakers, even in nearfield listening like me, is imperative ...

Here is my advice: 

Buy some big  empty wine bottles, or drink them before, it is optional....Or use some carafes, the kind that some display at the center of a table....I use plastic  wrapping sheets to tightly seal the aperture of the bottles and the carafes after pouring in them around 10 % of water in their volume space...You must listen and experiment for your taste and room to determine the exact amount of water to boost the frequencies that will benefit….After that  I peirce the plastic sheet with a needle and I insert a  thin straw with only the extremity of the straw at the top...  That its! You know have an Helhmotz resonator... 

You now have one of the more astounding tweak for a room that will transform your listening space in sound heaven ...I use more than 15 of them in my little audio room and trust me that is one of a kind upgrading...

I wrote that for those who want to experiment, the others can stay silent...My best to all...

Try the jerrican 5 gallons with 2 slush large straws inserted in one another and placed in the pierced  plastic sealed nozzle, that will equilibrate the frequencies toward the bass I promise... Just a little water in the jerrycan less than 10 %....It makes wonder all these resonators and by the way I use 20 types of stones and crystals in a connected grid on my audio system and in my electrical grid...All that push my system each times to more quality... But now it is I think impossible to makes all that I have sound better...
In audio price is not linearly connected to quality sound …. Tweaking already hi-fi used or vintage pieces of gear is the key to paradise...The Helmoltz resonators is astounding, but with some experiments... 
is your room already treated with absorber and reflector of sound? perhaps your room is already too much resonant and reflective and the resonator makes all that thin? My room was already treated by me before the adding resonators...There is some order to work with these tweaks...Room treatment first... Resonator second...
As some have suggested, could you post a picture of one of your actual resonators? Especially of the straw inserted, and how far into the plastic you have it inserted? You posted that you have "only the extremity of the straw at the top", and I am not sure what you mean by that. Thanks for your help and suggestions!
Simple if you experiment just a little... 2 inches max,  out of the nozzle...The straw  is only put trough the pierced plastic sheet paper wrap used in kitchen...I put elastic to tight it around the nozzle...No need of photo for that... And I cannot put photos here even if I wanted to...I apologize for that.... I will be here to answer your question...My best to you...
